 ## 1, Popup element misaligned and flipped in wujie micro front-end

+**Reason:** The popup element has a boundary detection logic, and in sub applications, the width and height of 'window' may be much smaller than that of the viewport,
 therefore, it can misjudge boundaries, leading to issues such as flipping and misalignment.

+## 2、In the 'Vitepress' project, reference the 'Opentiny' component package and use the 'Vitepress' packaging command: 'pnpm docs:build' ， Causing error: 'ERR_UNSUPPORTED_DIR_IMPORT'
+
+**Reason:** Unable to find the 'js/css/...' files referenced within the component package waiting for suffix path, error statement: 'Error [ERR_UNSUPPORTED_DIR_IMPORT]: Directory import "xxx" is not supported resolving ES modules imported from xxx/lib/index.js'
+
+**Solution:** In the '. vitepress/config. js' file, add the following code:
+
+```js
+export default defineConfig({
+  vite: {
+    // ...
+    ssr: {
+      noExternal: [/@opentiny\//]
+    }

 ## 1、弹出元素在无界微前端中发生错位、翻转
